Turn the hair dryer on the highest heat setting and apply heat to one corner of the tint for two or three minutes. The heat from the hair dryer will loosen the glue that holds the tint to the window. Look for a corner that may already have worked loose or started peeling, and choose that corner as your starting point.
Pry one corner of the heated tinting slowly and gently from the surface. Use the razor blade to loosen the tint if necessary by sliding it under the tint and scraping it from the window glass so you can grab hold of it.
Continue applying heat from the hair dryer to the window tint. Grasp the tint firmly and pull it from the window in a slow, even movement, keeping it close to the surface of the window instead of pulling it up and away.
Apply the citrus-based adhesive remover to a paper towel and rub any remaining glue spots with it. The citrus oil will easily remove any adhesive that was left behind with some elbow grease.
Spray the window thoroughly with the window cleaner. Use paper towels to clean the window until it is restored to its pretint condition.
